It's the version that comes with SuSE 7.2, and it doesn't give any version
information when loading:

   root@fox:/home/franz/vdr/DVB/driver > insmod i2c-core
   Using /lib/modules/2.4.4-4GB/kernel/drivers/i2c/i2c-core.o
   root@fox:/home/franz/vdr/DVB/driver > tail /var/log/messages
   ...
   Sep 29 15:43:27 fox kernel: i2c-core.o: i2c core module

Maybe this helps:

   franz@fox:/usr/src/linux > ls -l drivers/i2c/i2c-core.c
   -rw-r--r--    1 franz    users       37877 May 15 19:39 drivers/i2c/i2c-core.c
   franz@fox:/usr/src/linux > sum drivers/i2c/i2c-core.c
   63063    37

This is all very odd because the same DVB driver runs perfectly on SuSE 7.1
with kernel 2.4.0. I wonder what could have changed so dramatically between
these two kernel versions, that has these bad effects on the saa7146_core.o
module...
